TECHNICAL SPECIFICATIONS
ENGINE HYDRAULIC SYSTEM
The e-EPOS (Electronic Power Optimising System) is the brain of
Model
the excavator - minimising fuel consumption and optimizing the
Doosan DL06P efficiency of the hydraulic system for all working conditions.
Designed to deliver superior performance and fuel efficiency, the To harmonise the operation of the engine and the hydraulics, the
Doosan Stage IV diesel engine fully meets the latest emissions e-EPOS is connected to the engine’s electronic control unit (ECU)
regulations. To optimise machine performance, the engine uses via a data transfer link.

CAB
The air-conditioning and heating systems are integrated for
optimal climate control.
An automatically-controlled fan supplies the pressurised and
filtered cab air, which is distributed throughout the cab from
multiple vents.
The heated air suspension, adjustable operator’s seat includes a
seat belt. The operator can adjust the ergonomic seat and joystick
console separately according to his preferences.
